SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 230,026, dated July 13,1880. Application filed January 5, 1880.

To all whom t't may concern Be it known that I, LYDIA J. LANPEERE, ofVaterloo, in the county of Black Hawk and State of Iowa, have inventedcertain new and useful Improvements in Shutter Workers; and I do herebydeclare that the following is a full, clear, and exact description oftheinvention, which will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a partofthis specification.

This invention has for its object to furnishv a simple, cheap, anddurable shutter-worker.

I will first describe my invention, and then specifically point it outin the claim,

In the drawings, Figures 1 and 2 are horizontal sections of a windowframe and shutter with my invent-ion attached thereto, showing theshutter open and closed. Fig. Sis a front view of a portion of a'windowframe and shutter with my invention applied thereto.

(t is the windoweasin g. b is the shutter, and c represents the lowerhinge of the shutter.

The upper hinge may be of any ordinary form. The invention is appliedonly to the lower hinge.

The casing a has a horizontal mortise, a', in which is placed a slidingbar, d, on the outer end of which is formed a rack, d. Ihe rack d hasthe cog cl2 next the last at its outer end formed with a flat top orend, as shown, and has the cog cl3 next the last at its inner endsimilarly formed. The end cogs ofthe rack have a slightly wider spacebetween them and the cogs d2 d3 than is between the other cogs thereon.The object of this is to permit the fiat-top cogs to pass onto the topof corresponding cogs on the pinion of this hinge, hereinafterdescribed.

The lower leaf, o', of the hinge has a projection and guide-pin, c2,arranged so that the back of the bar d will bear against it. This pin isemployed so that less accuracy need be observed in forming the mortisea. The bar can be supported by the side of the mortise;

but this would require great nicety in forming said mortise withreference to the hinge. The use of the pin c2 obviates this exactnessinconstruction.

On the knuckle c4 of the leaf c3 I form a pinion, e, which is engaged bythe rack el on the rack-bar el. On opposite sides of the pinion I formtwo flat-top cogs, e e2, so arranged that they will engage on the topsof the cogs cl2 cl3, as hereinafter explained.

I have shown the pintle of the hinges c attached to the leaf c3; butthis is done for convenience. The pintle may be put on the leaf y o anda hole formed through the pinion c to rest over it.

The operation of the device is very simple. In Fig. 1 the shutter isopen and locked by having' the teeth cl2 and .e2 with their endsabutting and the end stop-cog, d4, of the rack-bar pressed against thecog e3 of the pinion. Push the bar cl from the position in Fig. 1 to theposition shown in Fig. 2. The cog cl2 will be thrown off the cog e2, andthe rack will enga-ge the pinion and turn it, closing the shutter andbringing the end of the cog d3 to abut against the end of the pinion-coge and the stop-cog d5 against the side of the cog e, thereby looking theshutter.

Havingdescribed myinven tion, what Ici-aim 1s- The combination, with thehinge of a win dow-shutter and the frame a, of the pinion e, iXed to theleaf o3, and having the cogs e e2, formed with ilat ends and arranged asde scribed, and the rack-bar d. having the rack d with the dat-top cogsd2 d3 at its ends, and the stop-cogs Z4 d5, arranged to operate substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I afx my signature in'presence of two witnesses.
